 ### For multi user support: using the command **!addaccount** in the discord server the bot is used in, it will than dm you with the sign up process prompting you to enter your untis Username and password (no email neededd just untis username). The username is stored as plain text and the password is hashed on the device hosting the bot, so currently it is **not secure** since the host will have access to the hashed password and the hash used! Deleting an account is done by using **!removeaccount** which will delete the account and the password, created with your discord account

The bot may not send you a message if there is no lesson after the specified time so that you can leave empty lessons as is for the days
